Shields skin from UV
Undissolved zinc oxide particles cover the stratum corneum, scattering and reflecting UVB and UVA as a physical barrier. People in outdoor sun who worry about burn and photoaging feel that covered skin is less likely to redden at once.
Soothes eczematous, eroded skin
In diaper-rash and eczema ointments, zinc oxide is an astringent that takes up exudate and dries eroded surfaces. When an infant's bottom is red or an adult's skin fold is damp and pale, the feeling is mostly that the surface is less wet and sticky, with stinging easing as well.
